PanarexPlant Protection Product ComparisonPlant Protection Product ComparisonReport inaccuraciesReport inaccuracies

An emulsifiable concentrate formulation containing 40 g/L quizalofop-P-tefuryl (4.38 % w/w) for use as a selective, systemic foliar applied graminicide for use on specified broad-leaved crops for post-emergence control of a range of annual and perennial grass weeds, including volunteer cereals.

DIRECTIONS FOR USE
IMPORTANT : This information is approved as part of the Product Label. All instructions within this section must be read carefully to obtain safe and successful use of this product. Panarex has a built-in optimised wetting system and does not require the addition of tank-mixed surfactants, wetter systems or oils. Panarex is rapidly absorbed through the leaves and moves throughout the grass weeds to reach the growing points, above and below ground. First effects of Panarex can include stopping further weed growth and visible colour changes to the leaf tips at around seven days after application. Complete kill takes three to four weeks under normal good growing conditions.
On perennial weeds such as couch grass (Elymus repens), Panarex should be used under good growing conditions to optimise movement into all new growing points. Fragmenting the roots during cultivation of the seedbed can give better control of perennial weeds with extensive root systems.
Panarex is rainfast within one hour of application. Panarex is foliar acting and is not affected by soil type.
Panarex can be used on crops grown for processingGrass weeds germinating after application are not controlled. Panarex does not control broad-leaved weeds.
Panarex can contribute to the control of black-grass as part of a herbicide resistance management strategy, involving mixtures and sequences with herbicides of alternative modes of action. Where resistant biotypes are present control from Panarex will be unacceptable.
For cereal cover crops, spray Panarex when the cover crop has served its purpose, the risk of wind blow is passed and before the cover crop starts to seriously compete with the crop. Use high rates to effect rapid control and avoid crop competition.
For Common Couch Grass (Elymus repens) best results are achieved when the weed is actively growing and new rhizome growth commences.

Resistance
This product contains quizalofop-P-tefuryl which is an ACCase inhibitor, also classified as a Group [A] herbicide based on the mode of action classification system of the Herbicide Resistance Action Committee (HRAC). Strains of some annual grasses (e.g. black-grass, wild-oats, and Italian rye-grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer’.
Use only as part of a resistance management strategy that includes crop management, cultural methods of control. Panarex must not be used in mixture with any other product containing other “fop” (aryloxyphenoxypropionate) group of herbicides or in sequence with any other ACCase inhibitor herbicides within the same season and should be used in conjunction with other herbicides utilising multiple modes of action with overlapping weed spectrums in rotation, sequences, or mixtures. Where possible, use non-selective herbicides to control early flushes of weeds (prior to crop emergence). Avoid continued use of the same herbicide or herbicides having the same site of action in the same field unless it is integrated with other weed control practices. To reduce the risk of resistance developing, applications should be made to young actively growing weeds. Panarex should not be applied at doses lower than those recommended on the product label.
Monitor weed control effectiveness and investigate any odd patches of poor grass weed control.

Rate of use
0.5 to 2.25 l/ha. The application rate is dependent on the grass weed species, the size of weed, the weed density, the growth stage of the crop and competitive nature of the crop. (See Weeds table). Use the highest rate specified if the weeds are beyond the optimum growth stage for control or if the weed density is high. For best results apply when the weeds are actively growing and the leaves are at least 5 cm long.

Spray Preparation
Use only clean water for mixing. Half fill the spray-tank with water and start agitation. Add the required quantity of Panarex directly to the spray-tank or through a specialised filling device. Do not add any additional surfactants or oils to Panarex. Continue filling and maintain agitation during the entire spraying procedure, including travelling to the site and during stoppages. Rinse the container clean either with a pressure-rinsing device or by manually triple rinsing. Container washings should be added to the spray tank before filling is completed.

Water Volume
Panarex should be applied using a standard nozzle through conventional hydraulic equipment (including air-sleeved booms) at water volumes of 200 to 400 litres per hectare. The lowest water volume should only be used in open crops on small weeds. On later applications when the crop is dense or when weeds are larger, the spray volume should be increased to higher volumes to ensure adequate coverage of the weedsThe recommended spray pressure is 2 – 4 bars. Apply Panarex as a FINE or MEDIUM spray. Ensure the sprayer is correctly calibrated before use and the nozzles are in good condition. Blocked or worn nozzles can lead to uneven application and missed areas.

Recommendations
Only apply Panarex to actively growing weeds, especially in the spring with perennial weeds, when translocation to growing points on the rhizomes and stolons is important. Do not treat crops and weeds growing under stress. Stress can be caused by many factors including frost, drought, water logging, trace element deficiency, disease and pest attack.
